The aim of this study is the synthesis and the microstructural investigation of Al-Ce alloys, which can be a good alternative to commercial Al-Si alloys that can be used at a limited level especially in high temperature applications. Within this context, commercially available Al-9Si, Al-12.5Si and Al-18Si (wt. % Si) alloys and Al-13.5Ce, Al-18Ce and Al-27Ce (wt. % Ce) alloys were compared. While α-Al, eutectic Al-Si, primary Si structures were observed in Al-Si alloys; α-Al, eutectic fine Al11Ce3 and primary coarse Al11Ce3 intermetallic particles were identified in Al-Ce alloys. In addition, while Al11Ce3 phase decreased depending on the increase of added Ce amount in Al-Ce alloy, the amount and size of coarse Al11Ce3 intermetallic structures increased. The increase in the amount of alloying elements added to the alloy increased the hardness values of the alloys. When the hardness values of these two alloys group were compared, it was observed that the hardness values of Al-Ce alloys were lower than that of Al-Si alloys.
